MONTREAL — Jenrry Mejia was on the verge of getting at least one start with the Mets to begin the season, but those plans may have to wait.

The right-hander was drilled by a Ryan Goins one-hop, comebacker and departed Friday’s exhibition game against the Blue Jays with a contusion to his right forearm. Mejia was scheduled to have X-rays taken after the game.

“I walked out there and I don’t think I’ve seen a lump on a guy’s arm come up so fast,” manager Terry Collins said. “He got it pretty good.”

Mejia was likely to pitch on April 4 against the Reds, if healthy. But that spot would go to Daisuke Matsuzaka if Mejia is not available. Matsuzaka was lined up as insurance should Jon Niese not be ready to pitch on April 6. But the Mets likely would turn to John Lannan if Niese isn’t ready and Matsuzaka pitches on April 4.

“One thing we’re very lucky to have right now is some depth,” Collins said.

But the manager is encouraged that Niese felt “great” a day after throwing 59 pitches in a minor-league exhibition game. Niese is scheduled to pitch a minor-league game on Tuesday in Port St. Lucie that will determine if he can take his first turn in the rotation for the Mets.

Mejia pitched four-plus innings for the Mets and allowed one run on five hits, lowering his spring ERA to 2.70.

Gary Carter is still a big deal in this city.

Applause filled Olympic Stadium during a pregame ceremony in which the Hall of Fame catcher, who starred for the Expos and Mets, was remembered with a video tribute. Carter’s widow, Sandy, and daughter, Kimmy, joined his former Expos teammates Tim Raines, Warren Cromartie and Steve Rogers for the ceremony.

Carter died in February 2012 after a lengthy battle with brain cancer.

“This city always embraced Gary, embraced us as a family and I really felt that tonight,” Sandy Carter said.

She called it extra special that the Mets, who faced the Blue Jays in the first major league game at Olympic Stadium since 2004, were in the house.

“We love Montreal, but when we got traded there were some special years with the Mets, too,” Sandy Carter said.

Anthony Seratelli won’t be joining the Mets’ 25-man roster, according to Collins. The Seton Hall product was trying to stick as a backup infielder, but was hitting only .213 and had committed four errors. The Mets are expected to begin the season with Omar Quintanilla as the utility infielder.
